"That's how I know you're not possessed by a demon." She could be any number of other things, but demon was his first and biggest concern. He had a feeling cutting her with silver was going a bit too far. She'd passed the holy water test, he'd take it at face value and go with the assumption that like Jo, Jess really was back.
"When Dean came to ask me to help him find Dad, he said Dad was on a hunting trip." He still remembered the reaction from Jess, when he'd said he needed to talk to Dean alone, after Dean said that. before the hunting trip came up, he'd thought anything Dean said could be said in front of Jess. "Dad wasn't hunting game, or anything like that. He was hunting a Wendingo." He winced, because he knew she was going to ask what a Wendingo was. "They're evil creatures, once human, but cursed to immortality. They're...cannibals. It's...that's the kind of things we hunt, Jess." He knew he was giving her too much information, she couldn't possibly take it all in. "And when I got home, it was too late. A demon had decided to kill you. You were already gone."
